Evaluation

 

Resultado de aprendizaje Sistema de evaluación Peso (%) Carácter recuperable
Know the fundamentals of combinational and sequential circuits Analyze synchronous and asynchronous digital electronic circuits Know and apply hardware description languages Understand the necessary analog-digital and digital-analog interfaces in a specific application two written partial exams and an extraordinary exam for those who fail  75  Yes
Know the fundamentals of combinational and sequential circuits Analyze synchronous and asynchronous digital electronic circuits Know and apply hardware description languages Practical sessions, reports and a practice exam  25  No

 

1. The part of theoretical concepts and exercises is worth 75% of the global score. It is composed of two exams, one in the middle of the semester:

- first partial exam: chapters 1 to 5 (30% of global score)

- second partial exam: chapters 6 to 10 (45% of global score)

To pass the course, it must be obtained at least a 40% score in the second partial exam.

In order to promote a continuous evaluation, the students will be able to submit throughout the semester the exercises proposed during theoretical classes. The score obtained will be added to the corresponding partial exam (one point per exercise submitted)

Example: if a student submits 2 exercises and obtains a 100% score in both exercises, the partial exam will be assessed for a maximum 80% score, and a 20% score, corresponding to the 2 exercises submitted, will be added to the global score.

2. The practical part of the subject has a weight of 25% of the total of the subject.

Attendance and completion of all practices is an essential requirement to have the right to the evaluation of the rest of the aspects of the subject (including theory and practices).

In these laboratory practices, the acquisition of the knowledge developed in the theoretical classes will be demonstrated through the implementation of designs proposed in the practice sessions.

Of the 25% of the practice grade, the practice reports and the assessment of the student's work in the laboratory will be worth 5%, and there will be a final practice exam that will be worth 20%.

The delivery of all the required practice reports on time will be mandatory. Failure to deliver reports within the required deadlines will lead to not being able to take the final practice exam.

3. Those students that have followed the continuous evaluation will be able to do the recovery exam (extraordinary evaluation), which will consist of a single exam where all the theoretical knowledge acquired during the semester will be assessed. This exam will be worth 75% of the global score. In this case, in order to pass the subject, it will be necessary to obtain a 50% score in the recovery exam.
